Show complete solutions, show ALL the steps in the hypothesis testing. here are the steps for hypothesis: answer in the form of: 1. state the null and alternative hypothesis (Ho and Ha) 2. decide on level of significance, a 3. collect data and compute the value of the test statistics from the sample data. 4. make the decision. reject Ho if the value of the test statistics belongs in the critical region. otherwise, reject Ho | compute for the p value and make decisions. reject Ho if the p value is greater than or equal to a. otherwise, do not reject Ho. 5. interpret the results.

The deflection temperature under load for two different types of plastic pipe is being investigated. Two random samples of 15 pipe specimens are tested, and the deflection temperatures observed are as follows (in °F): Type 1: Type 2: 206 188 205 187 194 193 207 185 189 213 192 210 194 178 205 177 197 206 192 198 188 197 201 180 189 203 176 185 200 192 Do the data support the claim that the deflection temperature under load for type 2 pipe exceeds that of type 1? Assume normality and equal variances. Use a = 0.05.
